That would work for basically static data. At this point a special file in /proc might work just as well.

Having the data tables readable from /proc sounds unattractive due to this part from the article:

"The UTF-8 patches incorporate these rules by processing the provided files into a data structure in a C header file. A fair amount of space is then regained by removing the information for decomposing Hangul (Korean) code points into their base components, since this is a task that can be done algorithmically as well."

Exporting these non-standard tables to userspace would lock in this custom format implementation detail forever.
